This is an analysis from photos and videos of the 3kW machine's sector's geometry.
The point of this analysis is to be able to make grids that closely match the
testatika so that similar frequencies will be generated.
Note that photos are shown below for the front disc. The same appears to be
the case for the back disc too.
How many sectors?
In the Methernitha video there is are two sequences where the discs of the
machine are NOT TURNING! One sequence shows the left side and the other
the right side. The following composite photo is made up of snapshots of
the two sequences put together along with some grafting so that an accurate
sector count can be made. It appears as if there are 48 sectors (previous
estimates by others said 50.) In fact, as you'll see from reading below, there
are actually 288 sectors, organized into 48 groups and with 48 wire grids attached
to the front of the sector groups.

Front sector is see through (at least when rotating)
Have a close look at the following picture. It is from the DVD version
of the Methernitha video and is also on the VHS version but is not on
the online version.

Some hints may be gotten from the following device which is shown in the
lab at Linden near the beginning of the amateur video. It occurs when
they are talking about multiple discs in tandem. No details about the device
are given though.
WARNING - Everything below this point is called into question as
a result of the above finding on the video of a sequence that shows that not only
is the front disc transparent but that this transparency means it is not covered
in sectors as assumed below.
Sectors near the disc edge
The following photo was taken of a video sequence where the disc was rotating
and so there is blurriness and the following is arguable. It appears as if
the sectors are grouped, 6 to a group, and a wire grid is attached to the front
of each group. Further support for this grouping, and also the shape of the wire grids,
can be seen above. Notice that the wire grids do not extend all the way to the center
of the disk.

From photos of the back disc, it also has the same arrangement of groups,
though it's not known if there are the same number of them. This means that
the sectors are on the sides of the discs that face each other and the wire
grids are facing outward. So the sectors would influence how the two
discs interact with each other and the wire grids would influence how
the discs interact with the various components on either side of the discs.
Sectors near the disc center
Next, the sectors seem to enter a black area on the disk and may reappear
at the center to form a mesh, as the following photo shows. Note that if
there are 100W resistors connecting the sectors near the center of the disk as
some say was stated by Paul Baumann (still being looked into) then the
black area is a likely place for the resistors to be.

Mesh at the center of the disk
Lastly, in keeping with the idea of meshes/grids everywhere, as stated above,
there is also a mesh at the center of the disc as the following photo shows.
Also at this point there is a grid in front of the mesh.
This same sort of grid in front of the sectors near the center is also
found on the single disk small machine as the following photo shows
(in fact a lot of components can be found in similiar places on both
machines.)
Resulting calculations
The following calculations start from the diagram above and are summarized in
the diagram below...
The common estimate for the diameter of the 3kw machine's discs is 500mm (50cm).
That gives a circumference of 1570mm. Dividing that by 48 groups gives
32.7mm for each group plus the space between it and the next group at the edge.
From the diagram above, the spacing between one group and the next is
6/35.5 * 32.7mm = 5.527mm. This means 6units = 5.527mm, so 1unit = 0.921mm/unit.
The width of a group is 29.5units * 0.921mm/unit = 27.17mm.
If we assume the 6 sectors span all the space behind the wire grid then we
have 6 sectors plus the 5 1mm (estimated) spaces between the sectors taking up 27.17mm.
So each sector is (27.17mm - (5 * 1mm)) / 6 = 3.7mm wide.
For b in the diagram above, the wire to wire distance is 10units * 0.921mm/unit = 9.21mm.
From the edge of the disc towards the center of the disc there are
14 of these wire-to-wire distances for each wire grid. These values are summarized
in the diagram below.
